RAILWAY-RAIL STAY.

Specification of Letters Patent.

Patented March 16, 1909.

To all whom it may concern: .Be it known that we, 1 'TALTER H-. CoTToNandfllnoivnis ,HnNnnnsoN, citizens ofthe United States, residing atChicago, in the county. of,Cook,.and- State of Illinois, have" inventeda newi and .useful Improvement in Ra1lway Rail-Stays, of which thefollowing isva specification;

This invention relates todevicesfor increasing the stability of railwaytracks.

The objects of thisinve'ntion are to provide means for anchoring therails to the ties in sucha manner as to prevent creeping with relationthereto, and furthermore, to dispense with the use of serrated orcorrugated steel jaws which cut into and weaken the rails. J

The inventlon further CODSISt-Sf OI means for grippingtherails in such amanner that when stress 13 applied from the tie the grip is 'augmentedthereby and furthermore, to

provide means for resisting almost its full capacity under slippingaction.

The device 1S illustrated in the accompanycation, and in which- Figure 11s a side elevation Fig. 2 18.2. plan; Fig. 3 is an end elevation, oneof the parts being shown in section; Fig. 4 is a view showing amodification; Fig. 5 is a view showing the normal condition of one ofthe members with relation to the rail; Fig. 6 is a force diagram,showing theoretically the application of stress on the jaws.

Referring now to the drawings in detail, numeral 10 designates a railwayrail, 11 a railway tie, 12 and 13 the rail engaging members, and l t aconnecting bolt. The members 12 and 13 engage the lower part of the railknown as the foot flange, and are provided with tie-engaging flanges 15and 16, depending therefrom on the side adjacent the tie. Thetie-engaging flanges 15 and 16 are preferably slightly curved andproject considerably from the main body of the members 12 and '13. Themembers 12 and 13 are provided with jaws 17, 18, 19 and 20;

inc drawings, forming a part of this specifithe center toward the sideremotefrom the tie-engaging flanges, These holes are adapted to receivea bolt 14, rovidcd with a nut '23 and preferably with a' lock washer 24.

A lip 25 on the member 13 serves to hold the bolt 14 from turning.

In Fig. 4 the bolt 14 is supplemented by a hook bolt 14 and the member13 is dispensed with. j

In Fig. 5 is shown the member 12in its normal condition beforeapplication to the rail. It will be noted that the angle between the twogripping faces of the jaws 1'7and l8 is more acute than the an lebetween the upper and lower faces of the oot flange ofthe rail-10. Bythis construction aneven dis tribution of stress throughout the entireengagingsurface of the jaws of the members. 12 and 13 results when theyare forced or driven to the position shown in Figs. 1 and The diagram Fi6 illustrates EL PPIOXI 'Tnately' the ratio between the stresses applied to the upper and lower surfaces of the foot flange and't-he stressapplied in forcing one of the members 12 or 13 to the position shown inFigs. 1 and 4.. It should be understood, however, that the angle betweenthe should not be strained beyondthe elastic limit.

In the application of this device, the members 12 and 13 are applied byhand to the foot flange of the rail, to the position shown in Fig.- 5,with the flanges 15 and 1'6, of course, set up against the tie; a sledgeor maul is used to drive said members-to the position shown in Figs. 1.and at; the bolt is next applied with the washer 24 and the nut screwedup tight.

It willbe noted that while stress to the flanges 15 and 16 from the tie11, thatthe 1110I11l061$911l to turn in the direction shown by thearrows in Fig. 2 the bolt-head and washer assuming pivotal points.action augments the grip of the .jaws' of members lQ and 13011 the rail.

What we claim as'our invention and desireto secureby Letters Patent is:

rail flange and a lateral tie engaging projecaws should not be tooacute, asthe metal is applied 4 This tion on the lower jaw; the angle.of the jaws beingmore acute than the angle of the upper and lower facesof the rail flange with which less thanthe an they are intended tocooperate and'means acting on the body of the member to bind 1t to therail flange.

2. In a railway rail stay, in combination, a

member having a pair of jaws for engaging a rail flange and a lateraltie-engaging projection on the lower jaw the angle of the jaws bein moreacute than the angle of the upper and Tower faces of the rail'flangewith which they are intended to cooperate and a bolt for connectin thebody of the member with the opposite ilange of the rail. I

3. In a railway rail stay, in combination, a member having a pair ofjaws for engaging a rail flange, the an le between thejaws being e ofthe upper and lower faces of the rail i iange to which the member is tobe applied, and a lateral projection on the lower jaw; and a boltconnecting the body of the membenwith the opposite flange of the rail.

4. In a railway rail stay, in combination; a member engaging the upperand lower surfaces only of the footflange of a railway rail, atie-engaging flange on said member, a bolt connecting the member to theopposite side body of the member.
